Airworthiness Directives; Rolls-Royce plc (RR) RB211-535E4 Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for Rolls-Royce (RR) RB211-535E4 series turbofan engines. That AD currently requires initial and repetitive inspections of the outer combustion case for cracks and possible removal. This proposed AD would require the same inspections, but would require using RR Mandatory Service Bulletin (MSB) RB.211-72-7775, Revision 3, dated April 9, 1999. This proposed AD results from RR issuing a revision to the MSB. We are proposing this AD to prevent an uncontained outer combustion case burst, which could result in damage to the airplane.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; M7 Aerospace LP Models SA226-AT, SA226-T, SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, and SA227-DC (C-26B) Airplanes
We propose to supersede Airworthiness Directive (AD) 2008-12- 16, which applies to certain M7 Aerospace LP SA226 and SA227 series airplanes. AD 2008-12-16 currently requires you to inspect wires and tube assemblies for chafing, arcing, or insufficient clearance between components. If chafing, arcing, or insufficient clearance between components is found, AD 2008-12-16 requires you to clear, repair, and/ or replace all chafed wires, components, and tube assemblies. AD 2008- 12-16 also requires you to cover the four-gauge wires leaving the battery box with firesleeving and secure them with a clamp. Since we issued AD 2008-12-16, M7 Aerospace LP has notified us that Model SA227- BC (C-26A) was inadvertently left out of the Applicability section of the AD and they updated some of the service information due to parts availability. Operators have also identified issues with model applicability that needed clarification. Consequently, this proposed AD would retain the actions of AD 2008-12-16, add Model SA227-BC (C-26A) to the Applicability section, and regroup the models for clarification. We are proposing this AD to detect and correct chafing of electrical wires, components, and tube assemblies. This condition could result in arcing of exposed wires with consequent burning of a hole in a hydraulic line or the bleed air line. This failure could lead to a hydraulic fluid leak and a possible fire in the engine nacelle compartment.
Proposed Amendment of Class E Airspace; Ironwood, MI
This action proposes to amend Class E airspace at Ironwood, MI. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Gogebic Iron County Airport, Ironwood, MI. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations at Gogebic Iron County Airport.
Civil Supersonic Aircraft Panel Discussion
This notice advises interested persons that the FAA is participating in a panel session on civil supersonic aircraft research. The session will include presentations on current research programs and a question and answer session for attendees. The FAA is seeking to raise public awareness of the continuing technological advances in supersonic aircraft technology aimed at reducing the intensity of sonic boom.
Update of August 2001 Overflight Fees
On December 17, 2008, the Acting Administrator of the Federal Aviation Administration (FAA) approved the Charter of an Aviation Rulemaking Committee (ARC) created for the purpose of consulting with the FAA regarding the cost of providing air traffic control and related services to overflights, and providing advice and recommendations to the Administrator regarding the future level of FAA's Overflight Fees. This Notice includes a copy of the Overflight Fees ARC Charter and information about how to request to participate as a member of the ARC.
RTCA Special Committee 147 Sixty Eighth Plenary: Minimum Operational Performance Standards for Traffic Alert and Collision Avoidance Systems Airborne Equipment
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 147: Minimum Operational Performance Standards for Traffic Alert and Collision Avoidance Systems Airborne Equipment.
Proposed Amendment and Establishment of Restricted Areas and Other Special Use Airspace, Avon Park Air Force Range; FL
This action proposes to restructure the special use airspace (SUA), consisting of restricted areas and military operations areas (MOA), at the Avon Park Air Force Range (APAFR), Florida. The proposed changes would provide additional restricted airspace needed for training in high altitude weapons releases and other hazardous activities, and would reconfigure the MOAs to contain nonhazardous flight operations. The changes would permit more realistic training in modern tactics to be conducted at the Range and enable more efficient use of the National Airspace System.
Proposed Establishment, Revision, and Removal of Area Navigation (RNAV) Routes; Alaska
This action proposes to establish twenty three Area Navigation (RNAV) routes, and revise fourteen RNAV routes, in the State of Alaska. Additionally, this action proposes to remove four existing routes that are no longer required. Q & T-routes are Air Traffic Service (ATS) routes, based on RNAV, for use by aircraft having instrument flight rules (IFR)-approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. The FAA is proposing this action to enhance safety and to improve the efficient use of the navigable airspace in Alaska.
Establishment of Class E Airspace; Nantucket, MA
This action proposes to modify Class E Airspace at Nantucket, MA. The development of new Standard Instrument Approach Procedures (SIAPs) and the evaluation of current procedures are requiring the establishment of Class E Surface airspace designated as an extension to Class D airspace. This action would encompass the SIAPs and enhance the safety and airspace management around the Nantucket Memorial Airport, MA.
